Benefits of technology

The invention is a device that can be used to temporarily occlude the aorta, which is the main blood vessel in the body. It has two main parts: a locator and an occlusion portion. The locator helps the user to know if the device is correctly positioned in the aorta, and the occlusion portion is expanded to block the blood flow. The locator is designed to expand to a smaller diameter than the occlusion portion, so it doesn't provide much resistance when placed in the aorta. This makes it easier to use and helps to ensure the device is correctly positioned.

Problems solved by technology

Existing solutions for blood vessel occlusion have various drawbacks, including surgical invasiveness and requirements for complex imaging and guidance of the device.

Embodiment Construction

,” one will understand how the features of the embodiments described herein provide advantages over existing systems, devices and methods for blood vessel occlusion.

[0014]The following disclosure describes non-limiting examples of some embodiments. For instance, other embodiments of the disclosed systems and methods may or may not include the features described herein. Moreover, disclosed advantages and benefits can apply only to certain embodiments of the invention and should not be used to limit the disclosure.

[0015]The present invention is directed to a temporary aortic occlusion device having an expandable locator portion and an expandable occlusion portion. The expandable locator portion assists a user in determining whether the distal end of the device has been advanced within a patient's aorta, and the occlusion portion is expanded to occlude the patient's aorta, preferably below the renal arteries.

[0016]In one embodiment, the locator portion has a maximum expansion diameter ...

Abstract

Blood vessel occlusion devices, systems and methods, in particular embodiments of devices for aortic occlusion. The device includes one or more locator portions and an occluder portion. The device is delivered via transcatheter delivery. The locator portion may be radially expanded using a handle and actuator at the proximal end of the delivery catheter. Tactile feedback from the locator portion is used to determine proper location of the occluder portion, for example within the abdominal aorta. The occluder is then radially expanded to occlude the vessel.
